ABSTRACT

The prevent invention relates to: a fondant comprising a sugar system made up of a first non-crystalline phase and a second crystalline phase, wherein the non-crystalline phase contains isomaltulose and sucrose and wherein the crystalline phase contains isomaltulose; a method for the production thereof; use of the fondant as icing, coating or filling for baked goods; and baked goods that are completely or partially coated with the fondant according to the invention.

The prevent invention relates to: a fondant comprising a sugar system made up of a first non-crystalline phase and a second crystalline phase, wherein the non-crystalline phase contains isomaltulose and sucrose and wherein the crystalline phase contains isomaltulose; a method for the production thereof; use of the fondant as icing, coating, or filling for baked goods; and baked goods that are completely or partially coated with the fondant according to the invention.

Fondant or confectioner's sugar is used to produce conventional pastry icings. The adding of additional ingredients such as other sugars, fats, sugar alcohols, thickeners, emulsifiers, dyes and flavors is possible.

Fondants are soft, pasty sugar compounds that are used themselves to produce various confections, as a filling, or as icing for foodstuffs and luxury foods. To produce a fondant, sucrose, glucose syrup, inverted sugar creams, and/or sugar alcohols, and water are used, for example. The compound is boiled and then processed into a soft paste via strong kneading and quick cool-down. Flavors or also foodstuff dyes can also be subsequently added. Fondant is usually produced by supersaturating a sugar solution, particularly a sucrose solution. Excess sucrose is dissolved in hot water, wherein the sugar remains dissolved once the solution cools down and thus forms a supersaturated solution. If seed crystals are added to a supersaturated solution, the dissolved sucrose precipitates out as crystals.

Before being used as icing on baked goods, for example, a fondant comprises a two-phase sugar system made up of a sugar-containing liquid—thus non-crystalline phase—and a phase containing crystalline sugar. In the prior art, the crystalline sugar in the fondant is created by precipitating out crystals from the liquid phase.

Fondant icing is often used to glaze baked goods or pastries, for example donuts. If a fondant based purely on sucrose is used, the storage stability or, respectively, the shelf life of the pastry is greatly limited since sucrose has a hygroscopic effect and the icing therefore becomes gooey during storage. In addition to fondants made of sucrose, fondants made of trehalose are also known in the prior art. Due to a high water content, however, trehalose as a solid tends to clump together and is therefore disadvantageous during processing.

DE 10 2010 055 577 A1 describes an isomaltulose-containing fondant having a non-crystalline phase made of glucose syrup. JP HS-89175 A describes various fondants based on isomaltulose or isomalt.

To summarize, conventional icings may become gooey because the moisture from the pastry migrates into the icing and/or the ambient humidity is absorbed into the packaging due to the hygroscopic property of the sucrose and other sugars (fructose, glucose). If the icing becomes gooey, it runs down the pastry and collects at the base of the packaging, which will reduce the microbiological stability. The pastry can also become dry due to this. In addition, conventional transparent icings may not remain transparent because the moisture from the icing migrates to a sweet pastry (for example a donut), such that the solubility of the sugar in the icing is reduced and may result in crystallization of the present sugar (blooming), and therefore to a clouding.

The technical problem upon which the present invention is based is therefore particularly to overcome the previously mentioned disadvantages, particularly to provide a fondant having high storage stability and low hygroscopicity after use (for example as an icing), and that is particularly suitable for use as a less gooey, preferably glossy, transparent foodstuff coating or as a filling. The technical problem upon which the present invention is based is also particularly to provide a fondant enabling a transparent icing—particularly an icing whose transparency is long-lasting—and an improved and simplified production method for such a fondant. In doing so, the fondant should preferably have sufficient sweetness, particularly without requiring that additional sweeteners necessarily be added.

The technical problem is achieved via the subject matters of the independent Claims, particularly via a fondant comprising a first non-crystalline phase and a second crystalline phase, wherein the non-crystalline phase contains isomaltulose and sucrose and wherein the crystalline phase contains isomaltulose.

In the context of the present invention, the percentile proportions of the individual components indicated for a composition of components add up to 100%, i.e. the total composition, unless stated and/or obviously otherwise.

In the context of the present invention, the term “fondant” is understood to be a two-phase sugar composition among other things, wherein the first phase is a non-crystalline phase and the second phase is a crystalline phase. According to the invention, a fondant is, among other things, usable as an icing or coating for foodstuffs, particularly baked goods and confections, wherein the fondant is thereby applied to the foodstuffs and subsequently dried. Before said use, the fondant is present in two-phase form as stated, wherein a person skilled in the art can determine the quantity proportions of the phases and the carbohydrates respectively contained therein, particularly sugars such as sucrose and isomaltulose. After application and drying, the fondant becomes an icing that is no longer two-phase. Unless stated otherwise, within the context of this invention the term “fondant” refers to the two-phase sugar composition before its use as (for example) icing or, respectively, before being dried.

Within the context of the present invention, the term “sugar system” is understood to be a mixture of at least two different sugars. Within the context of the present invention, the phrase “sugar system comprising a crystalline phase and a non-crystalline phase” refers, among other things, to a mixture of at least two sugars, wherein one of the sugars is at least partially crystalline and at least one of the other sugars is at least partially—particularly primarily or entirely non-crystalline, and is present particularly as a syrup, solution, or especially a saturated solution.

Surprisingly, it has been shown that the desired icing properties could be improved via a suitable mixing ratio comprising isomaltulose and sucrose hile using the physical/chemical properties and particularly also via application of a special production method.

It is been shown that the fondant according to the invention and the production method according to the invention can create an icing that is less gooey and can optionally also be transparent, and also will retain these properties for up to 8 days in the packaged state.

The low solubility of a sugar causes a high aw value, a reduced microbiological stability and increased risk of crystallization. The high solubility of a sugar causes a low aw value, an increased microbiological stability and reduced risk of crystallization.

The low hygroscopicity of a sugar causes low sensitivity to increased ambient humidity, a lesser degree of stickiness and improved packaging stability. The high hygroscopicity of a sugar causes high sensitivity to increased ambient humidity, a greater degree of stickiness and reduced packaging stability.

Surprisingly, it has been shown that the aw value of the icings or coatings produced from the fondants can be modified and set via the isomaltulose/sucrose ratios used in the fondants according to the invention.

In a particularly surprising manner it has been shown that, due to the isomaltulose/sucrose ratios used in the fondants according to the invention, the icings or coatings produced from the fondants have an aw value that is similar or identical to that of pastries. In this manner, the migration of moisture from the icing/coating to the pastry or from the pastry to the icing/coating can advantageously be reduced or suppressed.

The water activity (also known as aw value or Activity of Water) is an indicator of the freely available water in a material. It is defined as the ratio of the water vapor pressure in a material (p) to the water vapor pressure of pure water (p0) at a certain temperature. The aw value is normally considered an indicator of the shelf life of foodstuffs and influences the occurrence of microorganisms (spoilage microorganisms), which have differing demands on the freely available water.

Pastries, particularly deep-fried pastries, typically have an aw value of less than 0.95 and greater than 0.88. Donuts, for example, often have an aw value of about 0.91. It is now been shown that icings and coatings having such an aw value of less than 0.95 and greater than 0.88 can be achieved via the isomaltulose/sucrose ratios used according to the invention in the fondant, and particularly in the non-crystalline phase of the fondant. If pastries (particularly deep-fried pastries, especially donuts) are therefore combined with a fondant according to the invention (in particular if the fondant according to the invention is applied to such a pastry), a pastry with an icing or a coating is achieved in which the aw values of the pastry and the icing or the coating are similar or identical. In the context of the present invention, “similar aw values” preferably means a difference in the aw values of no more than 0.03, especially preferably a difference in the aw values of no more than 0.02. This will reduce or suppress the water migration between the icing or, respectively, the coating and the pastry so that the icing will not become sticky or crystallized over a longer timeframe, and the pastry also does not dry out due to increased dehydration. Given a transparent icing or a transparent coating, it is thereby especially advantageous if the contained sugar does not become crystallized, because otherwise the transparency is lost and the icing or the coating is no longer transparent and becomes milky.

The synergistic effect thus results that the icing or the coating on the one hand is less sticky during storage, and on the other hand remains transparent as needed.

In a preferred embodiment, the non-crystalline phase of the fondant according to the invention has an aw value of less than 0.95. In a preferred embodiment, the non-crystalline phase of the fondant according to the invention has an aw value of greater than 0.87. In a preferred embodiment, the non-crystalline phase of the fondant according to the invention has an aw value between 0.87 and 0.95. In a preferred embodiment, the non-crystalline phase of the fondant according to the invention has an aw value between 0.89 and 0.93. In a preferred embodiment, the non-crystalline phase of the fondant according to the invention has an aw value of about 0.91.

Surprisingly, it has also been shown that the aw value of the non-crystalline phase is not influenced by adding the isomaltulose in the crystalline phase.

It has also surprisingly been shown that the quantity proportions of sucrose and isomaltulose that are used according to the invention are sufficient for achieving sufficient sweetness of the fondant. Fondants according to the invention have about 50 to 70% of the sweetness potency of sucrose-based fondants. This results in a sweetness that is perceived to be pleasant and not too weak and that does not have to be enhanced. This is not the case when using trehalose. If needed, however, the sweetness can also be enhanced via the addition of fructose or sweeteners, for example.

In a preferred embodiment, the proportion of the non-crystalline phase in the total carbohydrate composition of the fondant (weight TS of the non-crystalline phase in relation to the total weight TS of the carbohydrates in the fondant) is from 30 to 70% by weight.

In the context of the present invention, “TS” refers to the dry substance. In the context of the present invention, “total weight TS of the carbohydrates” refers to the total weight of all sugars and sugar alcohols contained in the respective reference product, thus for example “non-crystalline phase,” “crystalline phase,” or “fondant.” If the respective reference product does not contain any sugar alcohols, the term “carbohydrates” refers to sugar. Accordingly, the phrase “total weight TS of the carbohydrates” may be replaced by “total weight TS of the sugars.”

Isomaltulose is a low-glycemic sucrose isomer which is also known under the name Palatinose™. In comparison to sucrose, isomaltulose has a sweetness potency of 40%. The solubility of isomaltulose is 32 g per 100 g water at 20° C., whereas sucrose has a solubility of 67 g per 100 g water. Contrary to sucrose, isomaltulose is only mildly hygroscopic. Isomaltulose is usually produced enzymatically via fermentation and is non-cariogenic. In a preferred embodiment, isomaltulose is used in the form of crystalline isomaltulose, wherein in a preferred form this can be present in powdered form. It is especially preferable if Palatinose™ PST-N (i.e. isomaltulose having a crystal particle size of 90% by weight<0.7 mm) or Palatinose™ PST-PA (i.e. an isomaltulose having a crystal particle size of 90% by weight <0.05 mm) is used. Alternatively, Palatinose™ PST-PF (i.e. isomaltulose having a crystal particle size of 90% by weight <0.1 mm) or Palatinose™ PAP-N (i.e. an isomaltulose having a crystal particle size of 90% by weight <0.7 mm) may also be used. Alternatively, the isomaltulose in the crystalline phase has a crystalline particle size of from 1 to 100 μm, particularly from 10 to 90 μm, 20 to 80 μm, 30 to 80 μm, 40 to 80 μm, or especially from 50 to 80 μm, or especially preferably from 10 to 60 μm, or particularly from 20 to 60 μm, or especially from 30 or 60 μm, or preferably from 10 to 50 μm, or particularly from 20 to 50 μm. The fondant according to the invention preferably has a crystal particle size of the isomaltulose in the crystalline phase of 90% by weight <0.7 mm. The fondant according to the invention preferably has a crystal particle size of the isomaltulose in the crystalline phase of 80% by weight >0.1 mm. The use of crystalline isomaltulose in these particle sizes leads to transparent fondants. Advantageously, isomaltulose as a solid with these crystal particle sizes has less of a tendency to clump together since the water content in an embodiment is only about 5%. This enables a better processing capability as compared to solely using trehalose in a fondant, the water content of which can be 10%.

In a preferred embodiment, the crystalline phase is coarse-grained. Small crystals degrade the transparency of the icing while coarse crystals will increase the transparency of the icing. Thus, it is desirable to use a coarse-grain crystalline phase if a transparent icing or a transparent coating is to be obtained from the fondant according to the invention.

In a preferred embodiment, at least 50% by weight or more preferably at least 75% by weight of the crystals in the crystalline phase have a granule size of at least 0.1 mm.

In a preferred embodiment, at least 80% by weight of the isomaltulose crystals in the crystalline phase have a granule size of at least 0.08 mm.

In a preferred embodiment, at least 80% by weight of the crystals in the crystalline phase have a granule size of at least 0.1 mm. In a preferred embodiment, at least 80% by weight of the isomaltulose crystals in the crystalline phase have a granule size of at least 0.1 mm.

Surprisingly, it has been found that, in a preferred embodiment, the fondant according to the invention results in a particularly homogenous, glossy, and transparent icing with coarse crystals on foodstuffs, for example baked goods, particularly deep-fried pastries. Even when using the fondants at 40 to 55° C.—for example on hot deep-fried pastries—quick drying of the icing on the pastry is ensured. Furthermore, the storage stability of the fondant according to the invention is increased significantly and the hygroscopicity is low. Advantageously, a coating resulting from the fondant according to the invention will absorb little to no water at all from the interior of the coated product and the ambient air. When used as a coating (for example as a glaze, thus a transparent coating), an especially low stickiness results.

In a preferred embodiment, at least 90% by weight of the crystals in the crystalline phase have a granule size of no more than 0.7 mm. In a preferred embodiment, at least 90% by weight of the isomaltulose crystals in the crystalline phase have a granule size of no more than 0.7 mm.

In a preferred embodiment, the non-crystalline phase contains at least 20% by weight isomaltulose (weight TS of the isomaltulose in the non-crystalline phase in relation to the total weight TS of the carbohydrates in the non-crystalline phase). In a preferred embodiment, the non-crystalline phase contains at least 45% by weight isomaltulose (weight TS of the isomaltulose in the non-crystalline phase in relation to the total weight TS of the carbohydrates in the non-crystalline phase).

In a preferred embodiment, the carbohydrate proportion of the non-crystalline phase is formed by at least 50% by weight of a mixture of isomaltulose and sucrose.

In an alternative embodiment, the fondant contains fructose, preferably in small quantities. In a preferred embodiment, the fondant contains no more than 3% by weight fructose. If necessary, the sweetness potency can be enhanced by the fructose.

The fondant may also contain polydextrose, preferably in small quantities, or particularly in a quantity of no more than 3% by weight. The fondant may also contain dextrins/maltodextrins (for example Nutriose®), preferably in small quantities, or particularly in a quantity of no more than 3% by weight.

In an alternative embodiment, the crystalline phase only contains traces of trehalose.

In a preferred embodiment, the crystalline phase contains less than 1% by weight trehalose.

In a preferred embodiment, the crystalline phase contains no trehalose.

In a preferred embodiment, the fondant only contains traces of trehalose. In a preferred embodiment, the fondant contains less than 1% by weight trehalose. In a preferred embodiment, the fondant contains no trehalose.

In an alternative embodiment, the fondant may also contain trehalose in the crystalline phase, in addition to isomaltulose. In one embodiment, the fondant may contain additional sugars—for example trehalulose—in addition to the previously mentioned sugars, namely isomaltulose, sucrose, and trehalose.

In a preferred embodiment, the fondant may also contain trehalose in the non-crystalline phase, in addition to sucrose and isomaltulose.

In a preferred embodiment, the fondant contains no sugar alcohols. In a preferred embodiment, the fondant only contains traces of sugar alcohols. Alternatively, however, the fondant may also contain sugar alcohols.

In a preferred embodiment of the present invention, the fondant does not have any sweetness potency enhancer or intensive sweetener. In an alternative embodiment of the present invention, the fondant only has traces of a sweetness potency enhancer or intensive sweetener. In an alternative embodiment of the present invention, the fondant has 0.0 to 3.0% by weight of at least one sweetness potency enhancer or intensive sweetener (total weight of sweetness potency enhancer or, respectively, intensive sweetener in relation to the dry substance of the fondant).

Nevertheless, the fondant according to the invention advantageously has a taste profile and most of all a sweetness potency that is sufficient for replacing conventional, pure sucrose-containing fondants.

In a preferred embodiment of the present invention, the fondant does not have any sugar substitutes, particularly no sugar alcohols and/or no intensive sweeteners, or has them only in trace amounts.

Within the context of the present invention, the term “traces” of a substance preferably refers to quantity proportions of less than 1% by weight, particularly less than 0.9% by weight, preferably less than 0.01% by weight.

In a preferred embodiment, the fondant contains 0.9 to 50% by weight water (in relation to the total weight of the fondant). In a preferred embodiment, the fondant contains 5 to 45% by weight water (in relation to the total weight of the fondant).

In an especially preferred embodiment, the fondant according to the invention contains from 10 to 40% by weight, preferably 15 to 35% by weight, especially preferably 10 to 30, preferably 15 to 30% by weight, particularly 15 to 25% by weight, especially 20 to 25% by weight water (in relation to the total weight of the fondant), particularly in the non-crystalline phase.

The quantity proportion of water preferably relates to the water added, but not to the water of crystallization contained in the sugars.

In a preferred embodiment, the fondant contains 0.01 to 1.0% by weight (total weight thickening agent in relation to TS of the fondant) thickening agent. In a preferred embodiment, the fondant contains 0.01 to 0.6% by weight (total weight thickening agent in relation to TS of the fondant) thickening agent. In a preferred embodiment of the present invention, the fondant contains 0.01 to 0.3% by weight, preferably 0.01 to 0.2% by weight, particularly 0.01 to 0.1% by weight) total weight thickening agent in relation to the dry substance of the fondant) of one or more thickening agents. The thickening agent is preferably selected from the group consisting of agar, carrageen, and xanthan. Agar is the particularly preferable thickening agent. The use of at least one thickening agent is of particular advantage, especially for using the fondant as a coating fondant. Advantageously, the recrystallization of components of the sugar system is prevented and the flexibility and stability of the coating is ensured, even over a longer time period. Moreover, the use of at least one thickening agent advantageously leads to an improved binding of the fondant to the foodstuff, particularly pastry. The binding of the crystals in the fondant can thereby also be improved.

In a preferred embodiment, the fondant contains 0.01 to 3% by weight (in relation to TS of the fondant) of at least one preservative approved for foodstuffs, at least one flavor, or both.

In a preferred embodiment, the fondant contains 0.01 to 3% by weight (total weight of acid in relation to TS of the fondant) of at least one organic acid approved for foodstuffs, one flavor, or both. The fondant according to the invention preferably contains 0.01 to 3% by weight, preferably 0.01 to 1% by weight, particularly 0.01 to 0.8% by weight (total weight of acid in relation to the dry substance of the fondant) of an organic acid approved for foodstuffs, a flavor, or both. It is especially preferable when the organic acid approved for foodstuffs is citric acid, sorbic acid, or lactobionic acid. The acids may also be added in the form of their salts, of course. The fondant according to the invention preferably contains 0.01 to 3% by weight, preferably 0.01 to 1% by weight, particularly 0.01 to 0.8% by weight (total weight of acid in relation to the dry substance of the fondant) citric acid. Such products are characterized by an especially balanced taste profile.

The fondant according to the invention preferably contains potassium sorbate. The fondant according to the invention preferably contains 0.01 to 3% by weight, preferably 0.01 to 1% by weight, particularly 0.01 to 0.8% by weight (total weight of acid in relation to the dry substance of the fondant) potassium sorbate.

It may also be provided that the fondant according to the invention contains food coloring.

In a preferred embodiment, a transparent glaze is formed from the fondant according to the invention. In a preferred embodiment, the fondant according to the invention is made transparent via drying.

The subject matter of the invention is also a method for producing a fondant, particularly a fondant according to the invention, wherein sucrose in a non-crystalline phase containing isomaltulose and water is dissolved in a first method step and, in a second method step, crystalline isomaltulose is added to the solution obtained in the first method step, thus obtaining a fondant.

In a preferred embodiment, the sucrose is added to a saturated isomaltulose solution in a first method step. By adding the sucrose, a small part of the dissolved isomaltulose is displaced and precipitated out as crystals. However, this quantity proportion of crystallized isomaltulose is very small and negligible in comparison to the quantity proportion of crystalline isomaltulose added in the second method step that does not dissolve in solution.

The method differs from conventional methods particularly in that the crystalline phase is not obtained via the precipitation of crystals, but rather via addition of crystalline isomaltulose to the non-crystalline phase. The crystalline isomaltulose does not dissolve, but rather remains in the crystalline phase.

The precipitation of crystals in conventional methods only results in fine crystals. However, these are not suitable for producing transparent icings from the fondants. However, by adding the isomaltulose crystals according to the invention, the crystal size can advantageously be freely selected and thus the later appearance of the icing formed from the fondant can be determined. Coarse isomaltulose crystals may also be added in the second method step so that a transparent icing can result from the fondant obtained.

In a preferred embodiment, crystalline isomaltulose is added in the second step, wherein at least 50% by weight, more preferably at least 75% by weight of the crystals have a granule size of at least 0.1 mm.

In a preferred embodiment, at least 80% by weight of the isomaltulose crystals have a granule size of at least 0.08 mm. In a preferred embodiment, at least 80% by weight of the crystals have a granule size of at least 0.1 mm. In a preferred embodiment, at least 80% by weight of the isomaltulose crystals have a granule size of at least 0.1 mm.

Preferred quantities and proportions of isomaltulose, sucrose, and other carbohydrates, sugars, and substances in the method according to the invention result from the preferred specifications for the fondant according to the invention.

It is especially preferable if the sucrose is added to the non-crystalline phase in the first method step and the crystalline isomaltulose is added to the non-crystalline phase in the second method step in quantity proportions such that the proportions between the isomaltulose and sucrose in the non-crystalline phase (in relation to the total weight of the isomaltulose and sucrose in the non-crystalline phase) ranges from 20 to 80 through 45 to 55, wherein at the same time the proportion between the isomaltulose and the sucrose in the fondant (in relation to the total weight of the isomaltulose and the sucrose in the fondant) ranges from 30 to 70 through 85 to 15.

A preferred embodiment of the method additionally includes the following steps:

-   -   f) adding at least one preservative and/or at least one organic         acid, preferably citric acid and/or potassium sorbate;     -   g) obtaining a fondant.

In an alternative embodiment, steps e) and f) may be switched. It may thus be provided that the at least one preservative is to be added to the solution tempered in step d) before the crystalline isomaltulose.

In alternative embodiment, at least one flavor may also be added. The at least one flavor may particularly be added in step f) in addition to the at least one preservative and/or the at least one organic acid.

In an alternative embodiment, steps a) and b) are replaced by the following steps a1) and b1):

-   -   a1) adding isomaltulose and a thickening agent to water;     -   b1) heating the water to 80 to 98″C until the thickening agent         and the isomaltulose has [sic] dissolved, whereby a         non-crystalline phase is obtained.

EXAMPLE 1: PRODUCTION METHOD FOR A FONDANT ACCORDING TO THE INVENTION

-   -   a) produce a saturated isomaltulose solution     -   b) add agar-agar as a thickening agent to the saturated         isomaltulose solution and heat to 95° C.     -   c) keep the preparation at 95° C. for 2 minutes in order for the         thickening agent (agar-agar) to completely dissolve;         subsequently compensate for water loss     -   d) add sucrose to sample and dissolve; maintain temperature at         about 60° C. (step for reducing aw value)     -   e) add the crystalline isomaltulose at 60° C.; the crystals do         not dissolve; the temperature reduces to about 50° C.     -   f) add citric acid and potassium sorbate

EXAMPLE 2: FORMULATIONS Formulation 1:

lsomaltulose for saturated solution: 10.8 g Isomaltulose for crystalline phase: 37.6 g Sucrose: 30.6 g Water: 20.5 g Agar-agar: 0.3 g Citric acid: 0.1 g Potassium sorbate: 0.1 g

Formulation 2:

Formulation 3:

lsomaltulose for saturated solution: 10.8 g lsomaltulose for crystalline phase: 45.3 g Sucrose: 22.9 g Water: 20.5 g Agar-agar: 0.3 g Citric acid: 0.1 g Potassium sorbate: 0.1 g

Formulation 4:

lsomaltulose for saturated solution: 10.8 g lsomaltulose for crystalline phase: 5.7 g Sucrose: 62.5 g Water: 20.5 g Agar-agar: 0.3 g Citric acid: 0.1 g Potassium sorbate: 0.1 g

Formulation 5:

lsomaltulose for saturated solution: 10.8 g lsomaltulose for crystalline phase: 60.6 g Sucrose: 7.6 g Water: 20.5 g Agar-agar: 0.3 g Citric acid: 0.1 g Potassium sorbate: 0.1 g

The weight and quantity specifications are based on g Hg (gram commercial weight). The bound water of crystallization is therefore also included in the specifications for isomaltulose.

The formulations were processed into fondants as shown in Example

-   -   1. The fondants were applied to donuts and dried as a glaze.

Formulations 1, 2, 3 are preferred. They lead to glazes that did not become sticky, showed no or hardly any moisture formation, and simultaneously showed no or hardly any worsening in the transparency over a storage time of 8 days.

EXAMPLE 3: CALCULATING THE SWEETNESS POTENCY OF FORMULATION 1

The sweetness potency of isomaltulose is 40%, which results in a factor of 0.4. The sweetness potency of sucrose is 100%, which results in a factor of 1. The calculation of the sweetness potency of formulation 1 is based on the commercial weight (HG).

Sweetness potency reference of glaze based on sucrose=71.4

Sweetness potency formulation 1=(10.8(quantity Hg isomaltulose saturated solution)×0.4)+(37.6(quantity Hg isomaltulose crystalline)×0.4)+(30.6(quantity sucrose)×1)

Sweetness potency formulation 1=(4.32)+(15.04)+(30.6)

Sweetness potency formulation 1=49.96

The glaze from formulation 1 thus achieves 70% of the sweetness of the reference sample.

The sweetness potency of formulation 1 leads to a pleasant and sufficient sweetness.
